How much heat is required to heat a 4 kg brick from 15 to 80 ° C?
| May 1, 2021 | education
Initial data: m (brick mass) = 4 kg; t1 (brick temperature before heating) = 15 ºС; t2 (final brick heating temperature) = 80 ºС.
Constants: Cк (specific heat capacity of a brick) = 880 J / (kg * ºС).
The amount of heat required to heat the brick is calculated by the formula: Q = Cк * m * (t2 – t1).
Let’s perform the calculation: Q = 880 * 4 * (80 – 15) = 880 * 4 * 65 = 228800 J (228.8 kJ).
Answer: To heat a brick, 228.8 kJ of heat is required.
